Natural Vs. Cultured Pearls – What’s the Difference?

When you hear people talk about natural pearls or cultured pearls it can be a little confusing at first. The important thing to remember is that the process by which the pearl is created is the main difference. They are both natural pearls (as opposed to fake pearls) and generally have the same qualities. However, should you get your hands on a natural pearl make sure to have it examined by a gemologist – they are extremely rare!

The rarity of natural pearls is due to their formative process. Basically, if an irritant such as a little bit of sand should come between the mantle and the shell of a mollusk, then it is sealed off and coated with many layers of nacre. It’s an oyster or other mollusk’s defense mechanism to protect itself! This doesn’t occur very often in the wild and even when it does it is very unlikely to form a perfectly round pearl. Apparently only one in 10,000 oysters ever produces a pearl like this so they are incredibly expensive.

Any time you buy a pearl necklace you are much more likely to be getting one made of cultured pearls. The cultivation process involves inserting some form of nucleus to stimulate the production of nacre. Saltwater pearls use a bead or shell nucleus, making them perfectly round but with a thinner layer of nacre. Freshwater oysters are nucleated with a small piece of mantle so they have thicker nacre but the shape is more likely to irregular. Basically culturing just means control over the whole process and has allowed for the mass production of pearls.

So are there any differences? The answer is no, not really! Both natural and cultured pearls have all the same qualities but you will rarely see natural pearls on the market. There’s no reason to be worried about the quality or authenticity of your cultured pearls. Enjoy them for their beauty and if you do happen to obtain a natural pearl, treasure it for its rarity.
